PETER M. KNOPP, OF KANSAS CITY, MISSOURI.

STEAM-MAKING APPARATUS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed January 30, 1906. Serial No. 298,638.

To all whom, t muy concern:

Be it known that I, PETER M. KNOPP, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Steam-Making Apparatus, of which the following is a specification.

My invention relates to improvements in steam-making apparatus.

The object of my invention is to provide a novel apparatus in which steam may be generated from water with great economy in the fuel employed for the purpose.

My invention provides a water-heating receptacle adapted to contain water under pressure and having a portion in which the Steam is generated and held under pressure, the receptacle at a place distant from the steam-generating portion having means for receiving a water-supply, combined with means by which a heating fluid, such as the products of combustion of the fuel, is conducted in contact with said receptacle and in a direction the reverse of that in which the water is conducted through the receptacle.

In its preferable form my invention comprises a furnace having at its lower end a firebox and at its upper end a smoke-stack, a plurality of boilers disposed one above the other in the furnace between the 'lire-box and the smoke-stack, flue-spaces being provided by which the products of combustion pass upwardly in contact successively with the boilers from the 'fire-box to the smoke-stack, the upper boiler having means for receiving the water-supply, and the lower boiler having means for discharging the steam formed therein, the boilers being connected in series by water-conductors.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a view of the apparatus, partly in vertical section and partly in side elevation. Fig. 2 is a cross-section on the dotted line a b of Fig. 1. Fig. 3 is a horizontal sectional view of boiler 6. Figs. 4 and 5 represent, respectively, longitudinal and transverse vertical sectional views of another form of my invention.

Similar characters of reference denote similar parts.

1 indicates the furnace-casing, 2 the fireboX located at the lower end and forward side of the casing, and 3 the smoke-stack at the forward side and upper end of the casing.

Referring to Figs. 1, 2, and 3, in the casing 1 is mounted a water and steam receptacle, comprising, preferably, the following described parts: 4, 5, and 6 denote, respectively, a plurality of horizontal boilers, disposed one above the otherbetween the fire-box and smoke-stack. The lower boiler 4 is the portion of the water-receptacle in which the steam is formed. Connected to the upper side of boiler 4 is the inner end of a pipe 7, which extends rearwardly through the back wall of the casing and carries olf the steam formed in boiler 4. The water-receptacle is supplied with water by a conductor 8, which has one end secured to the rear end adjacent to the lower side of boiler 6, the other end being connected to some source of water-supply outside of the casing. In conductor 8 is a shut-off valve 9.- 10 and 11 denote two water-conductors connecting the boilers 6 and 5 and 5 and 4, respectively. The upper ends of said conductors 10 and 11 are connected, respectively, to the upper sides of the boilers 6 and 5, preferably at opposite ends of said boilers. The lower ends of said conductors 10 and 11 are connected to opposite ends of the boilers 5 and 4, preferably adjacent the lower sides thereof. The boilers 4, 5, and 6 are preferably disposed so as to form flue-spaces 12 and 13 between said boilers, a flue-space 14 being provided below the boiler 4, and a liuc-space 15, which discharges into the smoke-stack 3, being provided between the casing and the upper side of the boiler 6. The boilers 4, 5, and 6 are so disposed that vertical connecting flue-spaces 16, 18, and 17 connect, respectively, the rear ends of flue-spaces 15 and 13, the forward ends of flue-spaces 13 and 12, and the rear ends of flue-spaces 12 and 14. 19, 20, and 21 denote, respectively, three conductors connected, respectively, to the lower sides of the boilers 6, 5, and 4, said conductors being connected outside the casing 1 to a vertical dischargeconductor 22. 23, 24, and 25 denote shutoff valves provided, respectively, in the con ductors 19, 20, and 21. A shut-off v alve 26 is provided in the conductor 22, below the conductor 21. The upper end of the conductor 22 is closed by a plug 27. 28 denotes the pipe connected to the upper side of the boiler 4, the other end of said pipe being connected to any suitable safety-valve. (Not shown.)

In the operation of my invention when fuel is burned in the fire-box 2 the heated IOO IIO

iuid resulting therefrom, comprising the products of combustion and hot air, passes rearwardly through the flue 14, under the boiler 4, thence upwardly through the fluespace 17 into the iue space 12, thence t rough flue-spaces 18, 13, 16, and 15 into the smoke-stack 3; Water passing inwardly through the conductor 8 will enter the boiler 6, pass from thence into the boiler 5 by means of K4conductor 10, and from the boiler 5 the water will pass by conductor 11 into the boiler 4, in which it will be converted into steam, which may be held under pressure and drawn off as desired through the steamconductor 7. It will thus be observed that the heated fluid resulting from the combustion in the fire-box will be conducted through the flues described to the smoke-stack 3 and in contact with the boilers 4, 5, and 6 in order the reverse to that in which the water is conveyed from the conductor 8 to the boiler 4, where the steam-is produced. By so conducting the heating iiuid the heat therefrom will be absorbed by colder portions of incoming water, so that a greater portion ofthe heat from the fluid passing out of the smoke-stack 3 will have been absorbed by the water. By the arrangement of the boilers and flue-spaces described the heating fluid is always in contact at any point with a portion of the water-receptacle having a lower degree of heat than the heat of the heating fluid at that particular point. Thus heat is never absorbed from the water pass ing through the receptacle by any part of the heating fluid, and great economy is therefore effected in the combustion of the fuel.

As shown in Figs. 1, 2, and 3, the boilers 5 and 6 may be provided each with two series of vertical bathe-plates 29, which extend from the top to the bottom of the boiler, one series projecting from one side Wall toward the opposite wall, but not quite to said opposite wall, the other series projecting in a like manner from said opposite wall past the adjacent ends of the other series of plates, the plates of the two series being disposed in alternate order relative to each other. By this construction the water in passing through boilers 5 and 6 is more quickly heated.

In the construction shown in Figs. 4 and 5 the water-receptacle comprises the following-described parts: Three boilers are shown, which correspond, respectively, in position to the boilers 4, 5, and 6. The lower boiler 4', corresponding to boiler 4 of Fig. 1, comprises two horizontal cylindrical parallel tubes 30 and 31, which extend rearwardly from the forward wall of the casing 1 toward but not reaching the rear wall. Trans- `verse water-pipe 32 connects the lower portions of tubes 30 and 31. A steam-pipe 7 is connected at one end to the upper side of tube 30 and extends laterally through the side wall of the casing. A vertical pipe 33 boiler 6 at the lower side of tube 36 of said' boiler and conducts water to said boiler from a source of supply outside the casing 1. A water-conductor 10 connects boilers 5 and 6, the upper end of said conductor being connected to the upper side of tube 35 of boiler 6 and the lower end connected to the lower side of tube 35 of boiler 5. A waterconductor 11 connects boilers 4 and 5, the upper end of conductor 11 being connected to the upper side of tube 36 of boiler 5 and the lower end being connected to the rear end of tube 31 adjacent the lower side there-v of. Horizontal arches 34, corresponding to the arches 34 between tubes 30 and 31, are

disposed between the upper sides of adjacent tubes 37 and between the side walls of the casing and the tubes 37 adjacent thereto. The arches 34 and tubes 30 and 31 and 37 form horizontal partitions, which form fluespaces between boilers 4, 5, and 6, corresponding to the flue-spaces 12, 13, and 15. (Shown in Fig. 1.) Draw-off conductors 19, 20, and 21, rcorresponding to the conductors already designated by such numerals, connect the boilers 6, 5, and 4, respectively, to a vertical discharge-conductor 22, already described with reference to the form shown in Fig. 1. A vertical flue-space 16 connects the rear ends of Hue-spaces 13 and 15. Vertical flueespace 17 connects the rear ends of flue-spaces 14 and 1.2, and a vertical fluespace 1S connects the forward ends of fluespaces 12 and 13. The flue-spaces 12, 13, 14, 15, 16, 1.7, and 18 correspond in location in the casing and in function with the iiuespaces having those indicating-numerals already described with reference to the form shown in Fig. 1. The boilers 4, 5, and 6 correspond also in location and function to the boilers 4, 5,.and 6 already described, and the mode of operation is the same as described with regard to the form shown in Fig. 1. The form shown in Figs. 4 and 5 is best adapted for making and retaining steam at high pressure, while that shown in Figs. 1, 2, and 3 is best qualified to make steam at low pressure. Any desirable means may be employed for supporting the boilers in their respective position. The water entering through the conductor 3 passes through the tube 36 of boiler 6, thence through the IOO IIO

tubes 37 and 35 of said boiler. From boiler 6 the water passes, by means or' conductor 10, into tube 35 of boiler 5, thence through tubes 37 of' said boiler to and through tube 36 of boiler 5.l From tube 36 the water passes through tube 1l into tube 30 of boiler 4, thence through pipe 32 into tube 31, the steam being made in tubes 30 and 3l. The heated products of combustion pass from the 'lire-box Z to the flue 3 through thev flue-spaces and in contact with boilers 4', 5', and 6, in the same manner as described with regard to the vform shown in Figs. l and 2.
